Background :Dysfunction in the kinetic chain caused by poor scapula stabilization can contribute to shoulder injuries and Shoulder Impingement Syndrome (SIS). The purpose of this study was to compare the effectiveness of two treatment approaches scapular stabilization based exercise therapy and physical therapy in patients with SIS.   Methods : The study is a randomized clinical trial in whic...

UNLABELLED The objective was to analyze the work activity and identify risk factors that could account for musculoskeletal disorders in the upper extremities, shoulder and neck of workers of a transport values company in Venezuela. The methods used were: collective interview, tasks observation, evaluation of posture with RULA method and evaluation of repetitive motions with the OCRA method. Fiv...

We sought to determine the effectiveness of head posture as a contextual cue to facilitate adaptive transitions in manual control during visuomotor distortions. Subjects performed arm pointing movements by drawing on a digitizing tablet, with targets and movement trajectories displayed in real time on a computer monitor. Adaptation was induced by presenting the trajectories in an altered gain f...

background: work-related musculoskeletal disorders are the most important problems in the health workforce. these discomforts cause many working days losses, increase absenteeism from work, and impose annual economic costs. awkward posture is the most important factor among the risk factors for work-related musculoskeletal disorders. this study aimed at implementing an interventional ergonomic ...

Substantial advancements in markerless motion capture accuracy exist, but discrepancies persist when measuring joint angles compared to those taken with a goniometer. This study integrates machine learning techniques capture, an aim enhance this accuracy. Two artificial intelligence-based libraries—MediaPipe and LightGBM—were employed executing shoulder abduction angle estimation. The of ten he...
